NUT-LOCK.

Patented April 16, 1907.

Application tiled February 2,1907. Serial No. 355,428.

To all 11a/1,0m it may concern:

Be it known that I, LUIS I-I. KENNEDY, a citizen of the United States,residing at Columbia, in the county of' Richland and State of SouthCarolina, have invented certain new and useful Improvements in NLit-Locks; and I dohereby declare the following to be a full, clear, andexact description of the invention, such as will enable Others skilledin the art to which it appertains to make and use saine, reference beinghad to the accompanying drawings, and to the letters and iigures otreference marked thereon, which form a part o'l this speciiication.

This invention relates to new and useful improvements in nut-locks, andconsists, es-

sentially, in the provision of a rod having a' series of plates hingedthereon and each apertured to receive a bolt and in the provision of aswinging plate having a recess with ilanged edges adapted to engage theopposite edges of a nut and preventy the same from turning upon the boltand means for holding recessed plates in engagement with the nuts.

My invention consists in various other details of' construction andcombinations and arrangements of parts, which will be hereinafterv fullydescribed and then specifically deiined in the appended claims.

I illustrate my invention in the accompanying drawings, in which- Figurel is a perspective view showing the application oi my nut-lock to therails of a railway and {ish-plate. Fig. 2 is a detail view of one of'the apertured plates -which is hinged upon a rod, and Fig. 3 is a detailview of one of the recessed plates with flanged edges.

Reference now being had to the details of the drawings by letter, A Adesignate the ends of two railway-rails; B, a fish-plate; C, boltspassing through the web portions of the rails and said fish-plate, and Dnuts upon the bo ts.

F designates plates, each of which is apertured to receive a bolt, andeach plate is turned into a roll G, hinged upon a rod I-I.

I I designate plates having recesses I formed in the lower swingingedges thereof, 5o and the opposite marginal edges of said re-` cessesare provided with outwardly-extending langes N, designed to engage theopposite edges of the nut. Said recessed plate is hinged to said rod andis movable thereon, as 5 5 `are also the plates F, whereby they may bemoved upon the rod to come in proper positions to engage the nuts in themanner shown.

M designates plates which are Similar to the plates F and hinged to saidrod, and each 6o is provided with a lug M which is bent at an angle tothe plate 'of which it forms an integral part and is apertured, as at T,to receive a rod R, which, passing through the apertures in the two lugsin the end plates IVI, is designed to engage the outer edges of theflanges upon Said plates and prevent the latter from swinging away fromthe nuts, thereby seeurely holding the plates in locking relation.V

From the foregoing it will-be noted that by the provision of a nut-lockmade as shown and described a simple and ethcient means is afforded foreifectually holding the nuts from turning upon the bolts and beingsimple in construction and easy of application may be adjusted to engagenuts positioned at different locations, the locking-plates being movablyheld upon said rod.

l. A nut-lock comprising, in combination with the rails and iiSh-plate,bolts passing through the same, nuts upon Said bolts, a Series ofapertured plates, a rod upon which the saine -are hinged, bolts'passingthrough the 85 aperture of each plate, a swinging recessed plate alsohinged to said rod, Ilanges upon the marginal edges of the recess insaid plate and adapted to engage the edges of the nuts, and a rodengaging the edges of said i'langes 90 and adapted to hold the latter inengagement with said nuts, as set forth.

2. A nut-lock comprising, in combination with the rails and iish-plate,bolts passing through the Same, nuts upon Said bolts, a series ofapertured plates, a rod upon which the rsame are hinged, bolts passingthrough the aperture of each plate, a swinging recessed plate alsohinged to said rod, flanges up on the In testimony whereof I hereuntoalliX my marginal edges of the recess in szd plate and signature in thepresence of' two Witnesses. ada ted to engage the edges of t e nuts,lugs f oarrgfing plates mounted upon said rod, and LUIS H' KENNED' aretaining-rod passing through the apertures /Vtnesses: of said lugs andadapted to engage the outer ROBT.
